Introduction

The steam boiler adopts the three return structure combined with the layout of the economizer and air preheater, recycles large quantity of condensing water during the production process. By making full use of waste heat of condensation water, the boiler still can ensure low exhaust temperature.

Features

Comprehensive Efficiency Higher than 95%

Low Operating Cost

Integrated Design covers Smaller Area

Low Smoke Temperature

Core technology

Auxiliary water to absorb flue gas temperature -- economizer

The high efficiency spiral finned tube is used for heat exchange, sufficient heat transfer surface, small resistance of flue gas side system, and effective control of fan power;

Enhanced heat transfer through aluminum fins on the outside, enhanced heat transfer on the inside, and efficient in both directions;

Solve the problem of combustion and water supply synchronization, reaching over 98%;

Set up the water filling tank, and use the soda water separation system to solve the problem of vaporization caused by the shortage of water supply of energy economizer;

The shell is ND steel, which can effectively reduce the corrosion of the cold and hot alternating working conditions during the stop furnace.

The air absorbs the flue gas temperature and makes the combustion more fully - the air preheater

Special aluminum tube, good plasticity, good sealing performance, strong heat and cold resistance of expanding mouth;

The low temperature corrosion capability of the fire resistance and stop furnace is strong;

High heat exchange coefficient;

The shell is ND steel, which can effectively reduce the corrosion of the cold and hot alternating working conditions during the stop furnace.
